Many studies classifying Gracilaria species for the exploitation of agarophytes and the development of the agar industry were conducted before the prevalence of molecular tools, resulting in the description of many species based solely on their morphology. Gracilaria firma and G. changii are among the commercially important agarophytes from the western Pacific; both feature branches with basal ...

Four seaweed polysaccharides were extracted from Sarcodia ceylonensis, Ulva lactuca L., Gracilaria lemaneiformis, and Durvillaea antarctica, respectively, by microwave-assisted extraction. The effect of three significant variables (extraction time, extraction temperature, and the ratio of water to raw material) on the process for extracting polysaccharides was investigated, along with the optim...

Oak lace bug ( Corythucha arcuata ) has continuously spread through Europe since its appearance in 2000, and it become a dangerous pest of Quercus species most countries. Despite high abundance the surrounding countries was found West Ukraine only 2020. During our investigation carried out 2020 OLB detected all studied large forest patches Ukrainian part Carpathian Lowland. These were one newes...

Our knowledge of non-native algae in benthic estuarine habitats is relatively poor, especially compared to algal introductions along open shores or on floating structures. Gracilaria vermiculophylla is a widespread macroalgal invader in the temperate estuaries of the Northern Hemisphere, and, here, we expand its documented range within northeastern Ireland and England. Established populations o...
